Description

Technical Field

[0002] A spraying device is a device that uses a fluid to eject at a certain speed through a nozzle and act on the surrounding medium. When processing nitrogen springs, in order to spray paint on the surface of the nitrogen spring, a spraying device is generally used to spray the paint into mist-like tiny particles, and a layer of paint film is evenly deposited on the surface of the nitrogen spring.

[0003] At present, when the existing spraying device is in use, when the workers are spraying paint on the surface of the nitrogen spring, the paint particles will be diffused in the air and inhaled into the lungs of the workers, which will affect the health of the workers and increase the threat to their health. In addition, after the spring is sprayed, the workers still need to disassemble it, causing the workers to come into direct contact with the freshly sprayed spring when unloading, increasing the chance of the new paint affecting the health of the workers.

By setting up a sealing unit, the working space of the spraying equipment can be sealed by using the sealing unit, thereby preventing the mist paint from floating to the space near the staff, thereby ensuring that the staff will not cause physical damage without taking preventive measures.

[0021] Six fisheye bearings 2102 are fixedly connected to the bottom surface of the rotating plate 2101, and the outer surface of each fisheye bearing 2102 is in contact with the top of the circular cylinder 1. By providing the fisheye bearings 2102, the fisheye bearings 2102 can provide support force to the rotating plate 2101 and the equipment above the rotating plate 2101, thereby reducing the pressure on the rotating shaft 15.

[0022] The top of the sealing cylinder 2104 is fixedly connected to a storage box 2105, the upper surface of the storage box 2105 is fixedly connected to an injection pipe 2107, and the outer surface of the injection pipe 2107 is threadedly connected to a threaded cover 2106. By providing the storage box 2105, the injection pipe 2107 and the threaded cover 2106, the storage box 2105 can be used to store a large amount of paint, and the injection pipe 2107 can replenish paint to the interior of the storage box 2105 at any time, and the threaded cover 2106 can ensure that no impurities enter the interior of the storage box 2105 when the injection pipe 2107 is not in use.

[0023] The upper surface of the sealing cylinder 2104 is fixedly connected to a gear pump 2109, and the input end of the gear pump 2109 is fixedly connected to an extraction pipe 2108. The left end of the extraction pipe 2108 passes through the storage box 2105 and extends to the interior of the storage box 2105. The output end of the gear pump 2109 is fixedly connected to a discharge pipe 2110, and the discharge pipe 2110 passes through the sealing cylinder 2104 and extends to the interior of the sealing cylinder 2104. The outer surface of the discharge pipe 2110 is fixedly connected to six nozzles 2111. By providing the gear pump 2109, the extraction pipe 2108, the discharge pipe 2110 and the nozzles 2111, the gear pump 2109, the extraction pipe 2108 and the discharge pipe 2110 can be used to extract the paint, and finally spray it around the nitrogen spring through the nozzles 2111, thereby completing the purpose of spraying.

[0024] The specific implementation of this embodiment is as follows: first, the stepper motor 14 and the gear pump 2109 are connected to the power supply respectively. When the power is connected, the device can be used normally. The operation of the stepper motor 14 will drive the rotating shaft 15 fixed at the output end and the rotating plate 2101 fixed at the top of the rotating shaft 15 to rotate, and the first clamping block 2103 is fixed on the inner wall of the rotating plate 2101. The first clamping block 2103 cooperates with the second clamping block 302 to clamp and limit the nitrogen spring to be sprayed, and cooperates with the rotation of the rotating plate 2101 to drive the nitrogen spring to move to the inside of the sealing cylinder 2104. When the rotating plate 2101 drives the first clamping block 2103 to rotate, the gear pump 2109 can be used as a stopper. The movable plate 2116 will rotate synchronously. When the transmission plate 2116 rotates to the position of one of the first transmission gear blocks 2117, the transmission plate 2116 will push one of the first transmission gear blocks 2117 to rotate. One of the first transmission gear blocks 2117 can transmit power to the other first transmission gear block 2117 under the drive of the transmission plate 2116, and cooperate with the meshing relationship between the second transmission gear block 2122 and the other first transmission gear block 2117 to drive the second fixed shaft 2114 to rotate, thereby driving the third transmission gear block 2120 fixed on the outer surface of the second fixed shaft 2114 to rotate. Because the outer surface of the third transmission gear block 2120 is in contact with the two gear plates 2126, the third transmission gear block 2120 is in contact with the outer surface of the second fixed shaft 2114. The outer surface of the gear plate 2126 is meshed with each other, thereby pushing the two gear plates 2126 and the first baffle 2112 and the second baffle 2123 fixedly connected to one side of the gear plate 2126 to move to both sides away from the third transmission gear block 2120. After the nitrogen spring rotates ninety degrees, the stepper motor 14 stops running. At this time, the transmission plate 2116 also stops transmitting the first transmission gear block 2117. At this time, the first baffle 2112 and the second baffle 2123 will block the two gaps opened on one side of the sealing cylinder 2104 under the push of the third transmission gear block 2120. Then, the gear pump 2109 is controlled to operate, and the gear pump 2109 drives the paint on the inner wall of the storage box 2105 to the discharge pipe 211 through the extraction pipe 2108. 0 until it is sprayed onto the surface of the nitrogen spring through the nozzle 2111. When the spraying is completed, the stepper motor 14 runs again. At this time, the transmission plate 2116 will be completely disengaged from the meshing relationship with the first transmission gear block 2117, and the first baffle 2112 will return to its original position under the action of the force spring 2113. When the first baffle 2112 is pulled back by the force spring 2113, it will also drive the third transmission gear block 2120, the second baffle 2123, the second transmission gear block 2122 and the first transmission gear block 2117 to rotate to their original positions, thereby effectively preventing the problem that small molecules of paint will float into the space around the staff when the device is in use, causing damage to the staff's body.

[0025] Example 2: Please refer to Figure 1-12The present invention provides a technical solution: a spraying device for nitrogen spring processing. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The protective mechanism 2 also includes a drying unit 22. The drying unit 22 is arranged above the circular cylinder 1. The sealing unit 21 is used in conjunction with the drying unit 22. The drying unit 22 can dry the sprayed spring.

[0026] As a further limitation of the air-drying unit 22 of the present invention, the air-drying unit 22 includes an air-drying cylinder 2201, the right side of the air-drying cylinder 2201 is fixedly connected to the left side of the sealing cylinder 2104, the left side of the storage box 2105 is fixedly connected to a fixed block 2205, the inner wall of the fixed block 2205 is fixedly connected to an air pump 2203, the input end of the air pump 2203 is fixedly connected to an air extraction pipe 2204, and the output end of the air pump 2203 is fixedly connected to a three-way exhaust pipe 2202, the three-way exhaust pipe 2202 passes through the air-drying cylinder 2201 and extends to the interior of the air-drying cylinder 2201. By setting up the air-drying unit, the air-drying unit can be used to air-dry the surface of the spring that has just been sprayed. In conjunction with the sealing unit, it can be more comprehensively ensured that the undried small molecule paint will only exist inside the sealing cylinder and will not appear in the space around the staff, thereby greatly reducing the possibility that the staff will inhale paint molecules into their body.

[0027] The upper surface of the storage box 2105 is fixedly connected to a transfer box 2206, the left side of the transfer box 2206 is fixedly connected to the right end of the exhaust pipe 2204, the inner wall of the transfer box 2206 is fixedly connected to four rectangular blocks 2210, and a filter 2207 is provided inside the transfer box 2206, the left side of the filter 2207 is in contact with the right side of the four rectangular blocks 2210. By providing the filter 2207, the air entering the interior of the transfer box 2206 can be filtered by the filter 2207 to prevent dust from entering the interior of the transfer box 2206.

[0028] The inner wall of the transfer box 2206 is rotatably connected to two rotating shafts 2209, and the right end of each rotating shaft 2209 is fixedly connected to a limiting plate 2208. The left side of each limiting plate 2208 is in contact with the right side of the filter 2207. By setting the limiting plate 2208 and the rotating shaft 2209, the rotating shaft 2209 can be used to drive the limiting plate 2208 to rotate, so as to decide whether to limit the filter 2207, making it convenient to disassemble the filter 2207.

[0029] The specific implementation method of this embodiment is as follows: after the paint is sprayed, the nitrogen spring that has been sprayed will be driven by the rotating plate 2101 to rotate to the inside of the air-drying cylinder 2201, and then the vacuum pump 2203 can be controlled to operate. The operation of the vacuum pump 2203 will drive the vacuum pipe 2204 to draw the outside air into the interior of the vacuum pump 2203, and then the gas can be discharged to the surrounding area of ​​the nitrogen spring that has just been sprayed with paint through the three-way exhaust pipe 2202, thereby accelerating the air flow and speeding up the drying of the paint on the outer surface of the nitrogen spring, thereby effectively avoiding the problem that when the device is in use, there will be a large number of undried paint molecules on the surface and surrounding area of ​​the newly processed nitrogen spring, which will still cause damage to the workers' lungs.

[0030] Example 3: Please refer to Figure 1-12 The present invention provides a technical solution: a spraying device for nitrogen spring processing. The present invention makes corresponding improvements to the technical problems mentioned in the background technology. The unloading mechanism 3 is arranged above the circular cylinder 1. The unloading mechanism 3 is used in conjunction with the protective mechanism 2. The unloading mechanism 3 can automatically unload the processed spring.

[0031] As a further limitation of the unloading mechanism 3 of the present invention, the unloading mechanism 3 includes an extrusion plate 305 and six buffer springs 303, the top of each buffer spring 303 is fixedly connected to a second clamping block 302, the outer surface of each second clamping block 302 is in contact with the inner wall of the rotating plate 2101, the upper surface of the extrusion plate 305 is fixedly connected to the inner top wall of the air-drying cylinder 2201, the bottom surface of the extrusion plate 305 is in contact with the upper surface of one of the second clamping blocks 302, the inner wall of the air-drying cylinder 2201 is fixedly connected to two guide plates 301, the inner wall of one of the guide plates 301 is fixedly connected to the outer surface of the extrusion plate 305, and the inner wall of the air-drying cylinder 2201 is fixedly connected There is a guide block 304, the front side of the guide block 304 and the back side of the guide block 304 are respectively fixedly connected to the side of the two guide plates 301 close to each other. By setting up a unloading mechanism 3, the unloading mechanism 3 can be used to automatically unload the processed springs, reducing the contact between workers and paint. Through the coordinated use of the sealing unit 21, the air drying unit 22 and the unloading mechanism 3, the problem that when the device is in use, tiny paint molecules are easily inhaled into the lungs by workers, posing a threat to the physical and mental health of workers can be effectively solved, and the purpose of automatic unloading can be achieved, thereby greatly avoiding the contact between workers and paint and ensuring that the workers' physical health is not threatened.

[0032] The specific implementation of this embodiment is as follows: when the paint has dried, the nitrogen spring will rotate between the two guide plates 301 under the drive of the rotating plate 2101. During the movement, the second clamping block 302 that fixes the nitrogen spring will gradually be squeezed toward the position of the buffer spring 303 under the action of the extrusion plate 305 until the second clamping block 302 loses its clamping effect on the nitrogen spring. At this time, the position of the extrusion plate 305 will not limit the nitrogen spring. The nitrogen spring will tilt toward the inside of the guide block 304 under the action of the wind discharged from the three-way exhaust pipe 2202, and slide downward along the guide block 304 until it slides into a separately prepared nitrogen spring storage device, thereby effectively avoiding the problem that the device does not have an automatic unloading function when in use, and the workers need to manually remove the processed nitrogen spring, which is inconvenient and increases the length of time the workers are in contact with the paint.
